Two vibrating tuning forks produce progressive waves given by `y_(1)=sin500pit` and `y_(2)=2sin506pit`. Number of beats produced per minute is:

A

360

B

180

C

3

D

60

Text Solution

Verified by Experts

The correct Answer is:
B
`f_(1)=(500pi)/(2pi)=250Hz`
`f_(2)=(506pi)/(2pi)=253Hz`
Hence, number of beats per minute = 180.
